Communication and Control, cont’d

Pacing and handshaking are not supported on captive screw connectors.

All of the bidirectional serial ports are completely software configurable. Baud rates can be set up to 115Kbs. Using the Simple Instruction Set (SIS) commands found in the Command/ Response Table for Simple Instruction Set later in this chapter, these ports can be configured to control most serial devices. Once a port is configured and properly cabled to the controlled device, serial commands can be issued to the port from a Web page, Telnet connection, or by using the advanced scripting capability built into the IP Link product family.

Communication with the Interface

Web server

The on-board Web server is displayed as a set of default Web pages which can be accessed via a Web browser. These pages are the primary means of communication with, and control through, the IPL T interface. Web browsers such as Netscape Navigator (version 6.0 or higher), or Internet Explorer (version

5.5or higher) can be used, but if using Internet Explorer, you must also have Microsoft Script (version 5.6 or higher).

The PC used to access the Web server must have a connection in common with the IPL T interface. In other words, both the unit and the PC should be connected to your local intranet or the Internet.

If you have established passwords for the interface, you will be shown a Password window when your browser accesses the IPL T unit (but not when you initially access the Web server, since no passwords have been established). Your level of control over the interface will depend on the password you enter in this password screen. If you enter the administrator’s password, you will have control of all matters of configuration. If you enter a user password, you will be restricted to control of A/V devices and viewing status.

Accessing and using the Web server

Logon and system status

1.Double click the Web browser icon on your Windows desktop to launch your Web browser.

2.Enter the IP address of the unit (see IPL T interface configuration in chapter 3) in the address field at the top of the screen and press the Enter key. The Password window (figure 4-8) is displayed if a password has been set (this

will not happen the first time you access the interface, as no password is set at the factory).

Figure 4-8 — Web server Password window

3.The System Status page (figure 4-9) is displayed, showing the current IP and port settings of the unit.

Establishing or changing system or port settings

The System Settings screen is used to initially configure or change configuration of the IPL T interface. You may be required to change system settings if your network changes, or if port settings change as you add or change display devices or switchers.

To configure system or port settings:

1.Select the Configuration tab and the System Settings screen (figure 4-10) is displayed.
